Trinitarian Bible Apologetics from Dr. Taylor Marshall :
The Trinity is one Substance and three divine Persons:
Mt 28:19 – Baptism is Trinitarian “I baptize you in the name (singular) of the Father, and of Son, and of Holy Spirit.”
***
Jesus is a Divine Person:
Jn 1:1 the Word was with God and the Word was God
Jn 8:58-59 – Before Abraham was, I AM
Jn 10:30 – Jesus “I and the Father are one."
Jn 20:28 – Jesus accepts Thomas’ words “My Lord and my
God!”
Col 2:9 – in [Jesus] dwells bodily the whole fullness of God
***
The Holy Spirit is a Divine Person
Jn 14:26 – the Holy Spririt will teach you all things
Acts 5:3-4 – lying to the Holy Spirit is lying to God
Acts 13:2 – “Holy Spirit said, ‘Set apart for me...’”
***
The Catholic Church teaches that Jesus is:
o Second Person of the Trinity
o One divine person with two natures (divine & human) o 100% divine (Son of God)
o 100% human (Son of Mary)
o Christ or Messiah (Son of David)
o Rose from the dead and is seated at Father’s right hand
***
HERESIES to avoid:
o Sabellianism (Modalism) exaggerates the oneness of the Father and the Son so as to make them but one Person. For modalists, the distinctions in the Holy Trinity are energies or modes, not Persons. For example, God the Father only *appears* on earth as Son. This is clearly a heresy, as Catholics and Orthodox believe in Three Eternal but distinct Persons in the Trinity.
o Docetism teaches that Jesus only appeared to be human. On the contrary, the Catholic Church teaches that Christ if fully God and fully man.
o Arianism teaches that Jesus not fully God. On the contrary, the Catholic Church teaches that Christ if fully God and fully man.
o Nestorianism teaches that Jesus is two “persons” - Jesus the human son of Mary and Jesus the divine Son of God. On the contrary, the Catholic Church teaches that Christ is one person with two natures: divine nature and human nature.
o Monophysitism teaches that Jesus is fully God but not fully man. The Catholic Church teaches that Christ has two natures: divine nature and human nature.
o Monothelitism teaches that Jesus has only one will. The Catholic Church teaches that Christ has two wills: a divine will and a human will belonging to His human soul.
o Iconoclasm teaches that images are idolatrous. On the contrary, the Catholic Church defends the use of Christian (not pagan) images since Christ became visible through the incarnation.
o Pelagianism denies original sin and teaches that grace is not necessary for salvation. The Catholic Church teaches that we are born in original sin and saved by grace through faith and works.
